| Abstract: | Rotational isomerism in enaminonitriles was studied using dynamic NMR spectroscopy and molecular modeling. It was found that the barrier to rotation about Cvinyl-NH bond was higher for enaminonitriles derived from aliphatic amines than that of enaminonitriles derived from aromatic amines. It was also found that the rotational isomerism about the Car-Cvinyl bond also exists in enaminonitriles. |
